Abstract

The invention provides an organic light emitting diode display and a manufacturing method thereof. An inorganic insulating layer covering a grid electrode is formed; an organic insulating layer is formed on the inorganic insulating layer to achieve a planarization effect; the problem of metal residue during etching of a subsequently formed metal layer due to an abrupt slope is avoided; a groove isformed in the position, corresponding to the grid electrode, of the organic insulating layer, a metal component used for forming a capacitor with the grid electrode is formed in the groove and arranged corresponding to the grid electrode, the distance between the grid electrode and the metal component is reduced, and the capacitance of the capacitor composed of the grid electrode and the metal component is large.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an organic light emitting diode display and a manufacturing method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED), due to its advantages of light weight, self-illumination, wide viewing angle, low driving voltage, high luminous efficiency, low power consumption and fast response, has been widely used. [0003] In the traditional technology, the scanning lines in OLED displays are made of molybdenum. Due to the high resistivity of molybdenum, in wide-screen OLED displays, the scanning lines made of molybdenum will cause delays in gate drive signals. Obviously, it is necessary to use a metal material with a small resistance to solve the problem of delay of the gate driving signal, and the metal material with a small resistivity includes aluminum. When the metal layer with lower resistivity is patterned by dry etching to form the gate of the t...
